Hi, I'mCustomer Welcome to JustAnswer. I'm reviewing your question now, and will post back with your reply ASAP.
Please do you have the latest version of Norton antivirus ? because Norton products works under Windows 7,8 and also Windows 10. To verify that you have the latest version of your Norton product, visit the Norton Update Center.
Would you like me to set up a remote session , which will allow me to connect directly to your screen and install Norton antivirus for you?
are you there please?
